On the basis of well known and widely used in mine practice retreat longwall mining system, physical and mathematical models of air leakage dynamics have been created. Flow is assumed viscous-inertial and considering natural anisotropy of porous media of a gob area. As a result of modeling pressure and leakage distribution and velocity field can be defined. Thus the model presented in this paper can be used as aerodynamical prediction of gob area characteristics.
